Clinical Trial Summary

Patients undergoing major surgery are at risk of postoperative complications. Continuous wireless monitoring outside the post-anesthesia or intensive care units may enable early detection of patient deterioration, but good accuracy of measurements is required.

This validation study, which is part of the WARD-SX project, aimed to assess the agreement between vital signs recorded by standard and novel wireless devices

Description:

Patients undergoing major surgery are at risk of postoperative complications. Complications may be preceded by abnormal vital signs. Standard monitoring at general wards is intermittent and manual, leaving the patients unobserved for extended periods.

The chance to enhance monitoring has arisen with recent technological advances in the form of small wearable and wireless devices that continuously record vital signs. Wearable devices enable continuous monitoring outside the intensive care unit and post-anesthesia care unit, thus enabling early detection of patient deterioration. However, before implementing such devices in hospital settings, good accuracy, and precision of measurements is required.

This validation study, which is part of the WARD-SX project, aimed to assess the agreement between vital signs recorded by standard and novel wireless devices

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Heart rate comparisons	Heart rate (beats per minute) measurements compared between Isansys Lifetouch and standard monitoring (Phillips IntelliVue). Analysed using Bland Altman (BA) analysis to measure mean diference and limits of agreement between to methods. The BA analysis is corrected for repeated measures within each subject.	1.5 hours (measurement interval every 15 min)
Primary	Respiratory rate comparisons	Respiratory rate (breaths per minute) measurements compared between Isansys Lifetouch and observed counted measurements. Analysed using Bland Altman (BA) analysis to measure mean difference and limits of agreement between to methods. The BA analysis is corrected for repeated measures within each subject.	1.5 hours
Primary	SpO2 measurements comparisons wireless vs. standard	SpO2 (percent) measurements compared between Nonin WristOx 3150 and standard monitoring. Analysed using Bland Altman (BA) analysis to measure mean difference and limits of agreement between to methods. The BA analysis is corrected for repeated measures within each subject.	1.5 hours (measurement interval every 15 min)
Primary	SpO2 measurements comparisons wireless vs. invasive	SpO2 (percent) measurements compared between Nonin WristOx 3150 and arterial arterial oxygen saturation. Analysed using Bland Altman (BA) analysis to measure mean difference and limits of agreement between to methods. The BA analysis is corrected for repeated measures within each subject.	1.5 hours
Primary	Pulse rate comparisons	Pulse rate measurements (beats per minute) measures compared between Nonin WristOx 3150 and standard monitoring. Analysed using Bland Altman (BA) analysis to measure mean difference and limits of agreement between to methods. The BA analysis is corrected for repeated measures within each subject.	1.5 hours
Primary	Blood pressure comparisons wireless vs. standard	Blood pressure (mmHg) measurements compared between Meditech BlueBp-05 and standard monitoring. Analysed using Bland Altman (BA) analysis to measure mean difference and limits of agreement between to methods. The BA analysis is corrected for repeated measures within each subject.	1.5 hours, every 15 min
Primary	Blood pressure comparisons, wireless vs. arterial BP	Systolic and diastolic (mmHg) measurements compared between Meditech BlueBp-05 and invasive arterial blood pressure. Analysed using Bland Altman (BA) analysis to measure mean difference and limits of agreement between to methods. The BA analysis is corrected for repeated measures within each subject.	1.5 hours
